FDA-compliant, stainless steel xiros® ball bearings in guide rollers for conveyor belts

• What was needed?  Electrostatically dissipative ball bearings
• Requirements: Electrostatic conductivity, freedom from lubrication and maintenance, FDA-compliant
• Material: xirodur F180
• Industry: Packaging technology
• Success for the customer:  xiros® plastic ball bearings have no complicated sealing concepts, therefore the bearings run continuously and without problems. xiros® F180 also provides the required electrostatically conductivity.

The problem was the conventional metal ball bearings used in the film guide rollers. They usually caused sparking, which should be avoided in packaging technology. Complicated sealing concepts that use lubricants also make metal ball bearings a food contamination hazard. The search focused on an electrostatically dissipative, lubrication-free alternative that operated smoothly.

The solution for the film guide rollers was xiros® ball bearings made of the xiros® F180 high-performance plastic. These bearings are not only 100% self-lubricating, but also ensure that sparks are obsolete due to the polymer used. The combination of polymer housing and stainless steel balls ensures  maintenance-free operation, and  FDA approval shows that it is suitable for food packaging.
